I tried to use a pattern on ravelry but the sizes didn’t seem right and then the gauge was wrong and I wanted a cardigan so I finally gave up and wrote my own. Make sure you swatch because I’m not sure at all the needle size is right. The cardigan is 9” at the neck opening and 12” long so feel free to increase or decrease to fit your dog. With it being a cardigan it’s way easy to make it a little tighter or looser with button placement. It’s a great single skein project!
